Rogue Science, a great website for all that knowledge that everyone thinks is "illegal" or such. The knowledge isn't, and the free flow of information is vital to not being defenseless when the crap hits the fan. Check it out.

As a side note, the IP of the site has been blocked by various organizations, so if you can't get to it, chances are your ISP/government (Germany is one)/school is blocking it. If you can, use a proxy server to get past it. Of course, if you're using AOL, Roguesci is blocking YOU.

http://www.bubbl.us/ is a little tool for helping creativity along. You can create bubbles linked into a tree, and organize content that way. It looks like a funny little thing to play with, so fool around, the controls are very easy.

What I'm missing is the possiblity of linking more things together from above... well, maybe in a further version. Also the auto-aligning goes sometimes against my design, but is easy to fix. Should the first thing be fixed some day, I may be even using it occassionaly - nothing about mapping out those many-scrolled submissions! (Plus it can be shared.)

MIT OpenCourseWare (MIT OCW) makes the course materials that are used in the teaching of almost all MIT’s undergraduate and graduate subjects available on the Web, free of charge, to any user anywhere in the world. This initiative continues the tradition at MIT, and in American higher education, of open dissemination of educational materials, philosophy, and modes of thought. Through November 1, 2006, MIT OCW has published 1550 courses.

PoisonAlchemist: Man Muro, you boost my confidence and then you just go crush it with a heartbreaking work of staggering genius.Pariah: Don't tell him things like that, if his head gets any bigger he'll float off like a weather ballon :p

A CAPTCHA is a program that can tell whether its user is a human or a computer. You've probably seen them — colorful images with distorted text at the bottom of Web registration forms. CAPTCHAs are used by many websites to prevent abuse from "bots," or automated programs usually written to generate spam. No computer program can read distorted text as well as humans can, so bots cannot navigate sites protected by CAPTCHAs.

About 60 million CAPTCHAs are solved by humans around the world every day. In each case, roughly ten seconds of human time are being spent. Individually, that's not a lot of time, but in aggregate these little puzzles consume more than 150,000 hours of work each day. What if we could make positive use of this human effort? reCAPTCHA does exactly that by channeling the effort spent solving CAPTCHAs online into "reading" books.

Ah yes, the wonderful article about social software and groupings online. I remember reading that a year or two ago. Amazing how stuff gets around on the 'net, eh?

And yeah, we are doing quite good by those standards. "Higher rank == more votes" and whatnot.

AG: Heck of a kid, aye? Seen it before, but it's still amazing. (On the other hand, my old trig teacher could do square roots of insane levels in his head. Admittedly, I think he was using a formula, or rules of square roots, but still quite amazing.)

Old, and hasn't been updated in a while, but a decent webpage for various activities that use different algorithms:

"Sick of hearing people name off algorithms that you should use, yet you have no clue what they are, much less how to implement them? Sick of people who won't take the time to explain algorithms and instead reference you to a book that you can't afford? Well, here's some info to help you out, for both the beginner and the advanced."

I found it quite helpful when I was looking up ray tracing, and I learned new stuff about exactly how some compression algorithms work.
